We're a casual society these days. Most men don't have to wear a suit all that often. But when the occasion calls for getting dressed up and you put in the effort—pulling on the jacket, knotting up a tie and tucking in a pocket square, you want to look damn good when you're done. So make sure you're not committing these all-too-common suit blunders.

Keeping It "Store Fresh"

You might see some guys wearing suits with the brand's fabric label still stitched to the bottom of the sleeve. You don't want that there. Take it off carefully with a small pair of scissors or a seam ripper, and do it as soon as you get your suit home. The same goes for the small threads (known as tack stitching) securing the vents and pockets. Those are only used to keep the jacket's shape while it's shipping and on the rack at the store.

Not Having It Tailored

When it comes to suits, the fit is the most important factor in how good you'll look in it. Maybe you've hit the jackpot and found a suit that fits almost perfectly right off the rack. That's fantastic. But trust us when we tell you that no matter how nice you think it looks now, a tailor will undoubtedly improve it—by nipping in the waist a bit or hemming the pants and sleeves to the ideal length.
